YAYA is cosplaying as Miku Hatsune from Vocaloid2. Miku Hatsune (初音ミク) is the first installment in the Vocaloid 2 Character Vocal Series released on August 31, 2007. The name of the title and the character of the software was chosen by combining Hatsu (初 First), Ne (音 Sound), and Miku (未来 Future). The data for the voice was created by actually sampling the voice of Japanese voice actress Saki Fujita. Unlike general purpose speech synthesizers, the software is tuned to create J-pop songs commonly heard in anime, but it is possible to create songs from other genres.
